6 Best Alternatives to the Dylesn 512GB iPhone ProRes Creator (2026)

How alternatives compare to Dylesn

iStorage diskAshur2 512GB Encrypted Portable SSD

The iStorage diskAshur2 shifts focus from raw speed to data security. It uses hardware encryption and password protection, which the Dylesn lacks. You give up the compact 0.2-inch form factor and high USB 3.2 Gen 2x2 speeds for a larger, heavier drive. This unit measures 3.15 by 4.72 inches and weighs 7.62 ounces. It is built for professionals handling regulated data who need physical protection and secure storage. If your priority is protecting sensitive files rather than recording 4K ProRes video on an iPhone, this encrypted drive is the safer choice. It sacrifices portability for robust security features.

Addlink S20 512GB 2.5-Inch SATA SSD

The Addlink S20 is an internal 2.5-inch SATA drive, not an external portable SSD. It uses a SATA III interface, which is significantly slower than the Dylesn’s USB 3.2 Gen 2x2 connection. You gain an SLC cache and 3D NAND technology for consistent performance in internal bays or custom external enclosures. The form factor is standard 2.5-inch, requiring a different mounting solution than the pocket-sized Dylesn. This drive fits users upgrading internal slots or building custom external setups. It does not support direct iPhone ProRes recording. It is a practical option for desktop upgrades where high-speed mobile transfer is not required.

Silicon Power A55 512GB 2.5-Inch SATA SSD

The Silicon Power A55 is another internal 2.5-inch SATA SSD. It connects via SATA III, offering lower transfer rates compared to the Dylesn’s USB 3.2 Gen 2x2 interface. It lacks the external portable design and iPhone compatibility of the original. The drive is designed for standard laptop and desktop upgrades. You prioritize capacity and compatibility over high-speed data movement. It does not include the shock-resistant casing or IP65 rating of the Dylesn. This drive is suitable for users who need reliable internal storage for everyday computing tasks. It is not a direct replacement for mobile video workflows or external backup needs.

Transcend 512GB PCIe 3.0 NVMe M.2 SSD

The Transcend MTE110S is an M.2 2280 NVMe drive using PCIe 3.0. It is an internal component, not an external portable SSD. It lacks the USB interface and iPhone connectivity of the Dylesn. You get PCIe 3.0 speeds with SLC caching, which is different from the USB 3.2 Gen 2x2 architecture. The form factor is small M.2, requiring a motherboard slot. It fits users needing reliable internal speeds without PCIe 4.0 hardware. It does not support direct video recording on iPhones. This drive is ideal for desktop or laptop internal upgrades. It sacrifices external portability and mobile device compatibility for internal system performance.

Transcend 512GB M.2 SATA SSD with DRAM

The Transcend M.2 SATA SSD is an internal M.2 2280 drive with a SATA III interface. It uses a DRAM cache for consistent performance. It is not an external portable drive and lacks USB connectivity. You cannot use it with an iPhone for ProRes recording. The drive is designed for compact systems where space is limited. It offers reliable SATA performance but does not match the external portability of the Dylesn. It is suitable for users needing a compact internal SATA drive. It sacrifices external use and mobile compatibility for internal system integration. It is a solid choice for space-constrained builds requiring DRAM caching.

Transcend 512GB M.2 2242 SATA SSD

The Transcend MTS430S is an M.2 2242 SATA SSD. It is a compact internal drive, not an external portable unit. It uses a SATA III interface and DRAM cache. It lacks the USB 3.2 Gen 2x2 interface and iPhone compatibility of the Dylesn. The 2242 form factor fits compact laptops and ultrabooks where larger drives do not. It provides reliable SATA performance for everyday tasks. You give up external portability and mobile video recording capabilities. It is designed for internal upgrades in space-constrained systems. This drive is practical for users needing small internal storage. It does not serve as a direct alternative for external mobile workflows.
